.2 Repainted interior surfaces shall be considered to lack uniformity and soundness if any of the following defects
are apparent to the Painting Inspection Agency inspector:
.a brush / roller marks, streaks, laps, runs, sags, drips, heavy stippling, hiding or shadowing by inefficient
application methods, skipped or missed areas, and foreign materials in paint coatings.
.b evidence of poor coverage at rivet heads, plate edges, lap joints, crevices, pockets, corners and reentrant
angles.
.c damage due to touching before paint is sufficiently dry or any other contributory cause.
.d damage due to application on moist surfaces or caused by inadequate protection from the weather.
.e damage and/or contamination of paint due to blown contaminants (dust, spray paint, etc.).
.3 Repainted interior surfaces shall be considered unacceptable if any of the following are evident under final
lighting source conditions:
.a visible defects are evident on vertical surfaces when viewed at 90 degrees to the surface from a
distance of 1000 mm (39”).
.b visible defects are evident on horizontal surfaces when viewed at 45 degrees to the surface from a
distance of 1000 mm (39”).
.c visible defects are evident on ceiling surfaces when viewed at 45 degrees to the surface.
.d when the final coat on any surface exhibits a lack of uniformity of sheen across full surface area.
.4 Repainted surfaces rejected by the inspector shall be made good at the expense of the Contractor. Small
affected areas may be touched up; large affected areas or areas without sufficient dry film thickness of paint
shall be repainted. Runs, sags of damaged paint shall be removed by scraper or by sanding prior to application
of paint.
3.7 Protection:
.1 Protect all newly painted exterior surfaces from rain and snow, condensation, contamination, dust, salt spray
and freezing temperatures until paint coatings are completely dry. Curing periods shall exceed the
manufacturer's recommended minimum time requirements.
.2 Erect barriers or screens and post signs to warn, limit or direct traffic away or around work area as required.
3.8 Clean-up:
.1 Remove all paint where spilled, splashed, splattered or sprayed as work progresses using means and materials
that are not detrimental to affected surfaces.
.2 Keep work area free from an unnecessary accumulation of tools, equipment, surplus materials and debris.
.3 Remove combustible rubbish materials and empty paint cans each day and safely dispose of same in
accordance with requirements of authorities having jurisdiction.
.4 Clean equipment and dispose of wash water / solvents as well as all other cleaning and protective materials
(e.g. rags, drop cloths, masking papers, etc.), paints, thinners, paint removers/strippers in accordance with the
safety requirements of authorities having jurisdiction.
